When needs carried out the gastric juice suction to the patient, take out the second body in by first body, after the through-hole that the elastic component embedding first body top of second body link set up, the second body is fixed, and the length of stomach tube extends to about 1.5 meters this moment. The end of the second tube opposite the connection end may be connected to the suction device by a second connector. The second connecting piece can be a connecting piece with the same structure as the first connecting piece. When the suction work is not needed, the elastic piece on the second pipe body is pushed to move towards the direction of the central axis of the first pipe body and press the second pipe body, and at the moment, the second pipe body is contracted into the first pipe body.
According to the technical scheme, the stomach tube in the above-mentioned embodiment is divided into two sections bodys of dismantling the connection with the body split, and first body is when using, and its length can not form the winding, and first body passes through the earmuff fixed, avoids the sticky tape to paste the pruritus that causes patient's skin. Simultaneously, the exchange of two sections bodys is used and can be satisfied and provide food and the two kinds of functions of stomach fluid suction, therefore the stomach tube in this embodiment have can compromise and provide food and stomach fluid suction, still can avoid partial pipeline must twine and paste the advantage in patient's face.
Further, in order to ensure the sanitation of the second pipe body and the food below the first pipe body, a third sealing plug 8 for sealing off the second pipe body is provided at the end of the second pipe body opposite to the connecting end.
Generally, the mouth of the second tube connected to the suction device has a large diameter. Generally, the diameter of an injection port of an injector for injecting food or nutrition is often smaller than the caliber of the top of the soft rubber tube, in order to ensure the sanitation of injecting food and prevent other impurities from entering the first tube body through a gap between the second tube body and the injection port, furthermore, the stomach tube in this embodiment is provided with a second injection hole having the same diameter as the injection port of the injector on a third sealing plug, and the third sealing plug is provided with a fourth sealing plug (not shown in the figure) for plugging the second injection hole.
It should be noted that the hidden structure formed by the first tube and the second tube in this application is only exemplary, and any structure capable of making the first tube and the second tube have the first length of, for example, 0.7-1 meter and the second length of, for example, 1.5 meters falls within the scope of the present invention.
According to the technical scheme, the gastric tube can be in two using states of only using the first tube body and the second tube body. When only using first body, the length of stomach tube can not form the winding, and first body passes through the earmuff fixed, avoids the sticky tape to paste and causes facial skin damage of patient, allergic pruritus. When the first pipe body and the second pipe body are used, the suction device can be connected with suction equipment to perform suction operation. Therefore, the stomach tube has the advantages that multiple functions of supplying enteral nutrient solution, taking medicines and other liquid foods, sucking gastric juice and decompressing stomach and intestine can be realized, the situation that part of pipelines are wound and stuck on the face of a patient can be avoided, and the risk of accidental tube drawing is reduced.
It will be understood that the invention is not limited to the precise arrangements described above and shown in the drawings and that various modifications and changes may be made without departing from the scope thereof. The scope of the invention is limited only by the appended claims.
